The international team find that rather than the conventional formation scenarios involving ‘normal’ matter, supermassive black holes could instead form […]

Scintillating discovery: These distant ‘baby’ black holes seem to be misbehaving — and experts are perplexed

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. Kathryn Ross, PhD Student, Curtin University Natasha Hurley-Walker, Radio Astronomer, Curtin University Radio images of the sky have revealed hundreds of “baby” and supermassive black holes in distant galaxies, with the galaxies’ light bouncing around in unexpected ways. […]

A map of 25,000 Supermassive Black Holes Across the Universe

The Low-Frequency Array (LOFAR) is a different kind of radio telescope. Although radio light has the longest wavelengths and lowest frequencies of the electromagnetic spectrum, much of radio astronomy has focused on the higher frequency end. Observatories such as ALMA study radio light at frequencies of hundreds of Gigahertz, and the VLA studies the fifty […]

Astronomers Make a Weird Discovery: A Concentration of Smaller Black Holes Lurking Where They Expected a Single Massive Black Hole

This is an artist’s impression created to visualize the concentration of black holes at the center of NGC 6397. In reality, the small black holes here are far too small for the direct observing capacities of any existing or planned future telescope, including Hubble. It is predicted that this core-collapsed globular cluster could be host […]
